May 9, 1933. D. P. MURPHY VALVE SERVICE RACK Filed July 29, 1932-Patented May 9, 1933 UNITED STA res rArNr VALVE SERVICE RACK Applicationled July 29,

My invention relates to novel and effective means to facilitate theoperation of reco`n ditioning the valves of an engine and moreparticularly to racks for holding the engine 5 parts removed incidentalto the operation and the materials used in theoperation conveniently ina position to facilitate the operation.

It is a Well recognized fact that in the op- 10 eration of valvegrinding, more effective and satisfactory results are secured in ashorter time with less expense if the valves are kept free from foreignmatter and in such order that they may bevreplaced in the same valveseats from which they Were removed With the expenditure of no Yothereort than that-re quired to partially disassemble the engine,- grind thevalves and replace the parts.

Heretofore it has been almostimpossible for a mechanic to keep thevalves in proper order, free from grit and foreign matter andconveniently separated due to the fact that no satisfactory means ofholding the parts and materials incidental to the grindingop* erationhas been provided Which Will be convenient to handle and mount upon theengine Y in an accessible position, which may bea part ofthe engineexposed incidental to the operation and Which Will stay in positionWithout the necessity of providing some special means for holding orsecuring the same in position.

A common device for this purpose Which mechanics have heretoforeresorted to Without much satisfaction or success is a stick of Wood witha series of holes drilled therein or some such other contrivance forreceiving the stems of the valves. However, these more or lessmake-shift devices have not proven '1 satisfactory for the reason thatthey provide no means of readilyfsecuring the device to any part of thecar or motor in a convenient position with the result that they arecontinually being knocked onto the floor With r the result that thevalves Will come in contact With foreign matter and may drop out orbecome damaged due to contact With the Vfloor surface or tools. w

Another difficulty often encountered in grinding the valves of aninternal .combus- 1932. Serial No. 626,245.

tion engine is the loss of some ofthe parts removed from the engineincidental to the grinding operation such as valve keys or pins sincethey are usually left lying around on any Hat surface `which must beused'in the 5,5 absence of proper holding means.

Vith the above mentioned and other. difficulties and annoyancesvincidental to the Operation of grinding the valves o-f'an engine, it isa primary object ofthe present inven- 60 tion to provide a rack forholding the valvesy i in consecutive order which' may readily be mountedsecurely upon the engine' block itself, if desired Without the use ofany special securing means Whatever. s

Another object of thel invention is to provide a `rack which Will becompact in conv .struction so as not to interfere With the movements ofthe mechanic in Working on the motor.

Still another object of the invention is to provide a rack Which Willhold a large number of valves and Which Will provide means for holdingthe valve keys and pins When they are removed. ,i775

A further object of the invention is to pros Y vide in said rack areceptacle for holding the valvevgrinding compound used in the grindingoperation and which must usually be left lying around in a small can. 39

A still .further object of the invention is to'provide all of thesefeatures in a rack which is highly eifective,extremely simple inconstruction, cheap to manufacture and Which may be produced ata veryloW cost. y

:Other objects and advantages of the invention Willbecome apparentYduring the course of the following detailed description of the inventionwhen read in conjunction With th-e accompanying drawing, Which forms 90a part of this specification and in *Which Y i Figure l is a perspectiveview of a preferred embodiment of the invention, and

Figure 2 is a central vertical sectional vieW thereof. y f5 Referringnow more particularly to the n drawing, wherein like numerals refer tolike parts throughout the sam-e, l0 indicates the valve rack which ispreferably formed from a single block of Wood although it could read-1GO ily be formed from metal if desired. The rack comprises asubstantially circular base portion 11, preferably several inches inheight and which terminates in an inclined ledge 12 extending entirelytherearound. The circular ledge 12 is terminated inwardly by a head orupper body portion 13 which is formed integral with the base or lowerbody portion but considerably less in circumference. This head portionhas the sides thereof tapered outwardly from the juncture with the ledge12 as at 14, and is formed on the circular edge of its upper face withan inclined ledge 15, which is of lesser inclination than the ledge 12.The flat top 16 of the head portion 13 is formed with a depression 17 inwhich is mounted a can 18 for holding valve grinding compound or thelike.y

A series of sockets or holes 19are drilled into the base portion 11,said sockets opening` on the ledge 12and being disposed at such aninclination to the vertical that their axes are at approximately rightangles to said ledge. Another series of sockets or holes 20 are 'drilledinto the head portion 13, said sockets opening upon the ledge 15 andalso having their axes approximately at right angles to said ledge.

It will thus be seen that the holes 2() more n-early approach thevertical than the holes 19 so that when the stems of valves are seatedtherein, the heads of the valves in the base sockets will clear thestems of the valves in i the head sockets.

The sockets will be numbered in consecutive order, in the embodimentshown, the head sockets being numbered from 1 to 10 and the base socketsfrom 11 to 24 so that this rack will accommodate the valves of anyengine,

open end of the sockets which receive the valve stems, thusAfacilitating the positioning of the valves therein and also dispose theindicia placed thereon to identify the sockets by number at such anangle as to be conveniently read.

For the purpose of holding the valve keys which are so often temporarilylost or misplaced, I provide a draw-er 21 in the base of the rack, sai-ddrawer preferably running entirely through from one side to the other sothat it can be opened from either end thereof.

In order to provide for securely mounting the rack on the engine block22, holes -23 are drilled in the bottom of the base to fit 'over thestud bolts 24 commonly carried by the motor block which are exposedincidental to the grinding operation. In the form of the invention shownthe holes 23 are shown as being preferably spaced to t over two spacedstuds but in case the'spacing of the studs varies, the rack can be heldjust as satisfact-orily on one stud.

For convenience in handling the rack when it is desired to carry thevalves to a refacing lathe or to move the rack for any purpose, a bailhandle 25 is provided, having the ends thereof pivot-ally secured insuitable ,openings on opposite sides of the head portion 13.

It will be noted that due to the angular setting of the holes 20, thevalve heads will be disposed a suficient distance from the can 18 topermit ready access thereto to reach the grinding compound therein.

-From the foregoing description, it will be readily apparent that I haveprovidedan extremely simple effective and inexpensive valve rack whichwill greatly facilitate the open ation of grinding motor valves andwhich overcomes'the difficulties theretofore encountered in the use ofkother'devices which have failed to accomplish the purpose for which theywere designed. f

While -a preferred embodiment of the Vinvention has been shown anddescribed, it will be understood that variousV modifications in thedetails of construction and in the selection of materials may beresorted to without departing from the spirit of the invention asdefinedin the appendedl claims.- "l

2. A valve service rack comprising a sub-y stantially circular baseportioniformed with an inclined annular ledge on its upper face and aseries of inclined sockets opening onto said ledge, a head portionrising centrally 'from said base portion and formed with an annularinclined' ledge bordering its upper face and a series of inclinedsockets opening into said ledge, said sockets in said head portion beingdisposed ata lesser inclination than those in said base; l y
